Our Focuses

Water Conservation

The average American family uses more than 300 gallons of water a day, which is costly to both the environment and your wallet. Midoori's water recycling technology can recycle water from showers, baths, laundries, bathroom sinks and HVAC systems for reuse in toilets and even outside irrigation. This saves between 40-85% of house water consumption, which is equivalent to 20,000 gallons a year annually. Not only does this reduce cost of living, but it also keeps water consumption to. a minimum.

Market Potential

ADUs not only increase housing density and provide affordable housing options but also offer property owners the opportunity to increase the value of their property and generate additional income. With the ease of construction and the growing popularity of ADUs, constructing these units using SIP construction can be a lucrative investment for property owners. As local governments incentivize the construction of ADUs, the market potential for these units is expected to increase in the coming years. Consequently, SIP homes and ADUs have become more accessible to builders and property owners, and the demand for them is on the rise.



Buildings account for 39% of total U.S. energy use and produce 38% of the country's carbon dioxide output. By installing a typical solar panel, you can save over 900 kg of CO2 annually, leading to significant financial savings. The carbon payback period for a solar panel is approximately 1.6 years, meaning that the renewable energy project will offset the greenhouse gases emitted during construction within a short period of time. Solar panels connected to a battery system can also reduce energy and carbon emissions throughout the night, resulting in even more savings for homeowners.

Res. & Materials.

Sustainable Materials

We prioritize sustainable materials in our construction process. Our on-campus paper clay mâché factory creates eco-friendly wall coverings. Recycled paper is blended in a container of water and eventually mixed with water-based glue and salt to create a strong forming wall covering. For exterior walls, we use high-performing slate rock cladding from CupaClad that's durable and has a modern look. Using sustainable materials reduces our environmental impact while ensuring high-quality homes.

Effective communication is essential in any construction project, and this is especially true when it comes to building ADUs. These structures are small in size, which means that every decision regarding their design and construction must be made with care and precision. In addition, sustainability is a critical consideration in ADU construction, as these structures are typically intended to serve as secondary residences that are energy-efficient and environmentally friendly. Clear and open communication between all stakeholders, including the homeowner, contractor, architect, and any other relevant parties, is essential to ensure that the ADU meets the needs and goals of everyone involved. By emphasizing effective communication and being transparent, Midoori strives to create a sustainable future together.

Op Savings

Operational Savings

Midoori’s west side green wall provides solar shading. It provides a 20 degree cooler wall than bare walls, which reduces energy usage, and in turn, reduces the effects of global warming. SIP homes are less prone to mold and dust mites due to their tight installation. Midoori’s low-slope roofing and tighter installation eliminates the need for a roof vent, which reduces HVAC system costs by up to 40%. These are just some of the concepts that our design implements to lower operation costs.

The Midoori home will be built using structural insulated panels (SIP), which have a higher R-value than traditional stick frame homes, making them more energy-efficient and reducing carbon dioxide emissions. SIPs use less materials than stick frame homes and are composed of oriented strand board and expanded polystyrene insulation, both of which are sustainable and recyclable. Vaproshield is used to protect the home from leakage and structural deterioration, while Cupaclad's slate cladding system is earthquake-resistant and energy-efficient. The home also incorporates paper clay mâché for partition walls, which is made with little to no toxic chemicals.
